TABLE OF CONTENTS Haloacetic acids.
Five haloacetic acids, monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monobromoacetic acids and dibromoacetic acids. The USEPA MCL in drinking water in the USA is 0.06 mg/l for HAA5.
Hormonally Active Agents. These are chemicals that affect the hormone system in humans. They are part of the group of chemicals that are endocrine disrupters.
The natural environment or location of a plant or animal.

In a radio-isotope, the time taken for half of its atoms to disintegrate to form another isotope. A pollutant, though not radioactive, also may have a half life.
A range of chemicals that have between one to three halogen atoms, e.g. chlorine or bromine, substituted into the methyl group ( CH 3) of acetic acid (CH 3COOH). They are used in industry for a range of purposes. They may also be disinfection by-products, produced during chlorination of water. They are probably carcinogenic to humans. The USEPA MCL in drinking water from 2002 for the total of five haloacetic acids...
